4.1. Signals Leads
Signals led out on the meter connectors are presented on the fig. 4.
All input signals are separated between them from remaining circuits.
Analog outputs are not separated between them. One don’t have to
take simultaneously advantage of voltage and current measure-
ments, since measuring circuits of voltage and current are not galva-
nically isolated.

DHB-202 / DHB-224
( Model DHB-224)
· 1 A, 5 A – terminals for the current measurement on the 1 A
or 5 A range.
· 100 V, 500 V – terminals for the voltage measurement on the 100 V
or 500 V range.
· OC –output of open collector type with an npn output transistor.
The output is turned on in case of a measuring range overflow.
